Web21 feb. 2024 · HR-defective status associated with greater dysfunction in remaining pathways such that at least three DDR pathways per patient are highly perturbed when HR pathways are defective. Web15 apr. 2024 · HR-defective cells are defined as samples that failed to achieve a 2-fold induction of RAD51-positve cells, a criterion used in previous studies that correlates with HR defects and PARP inhibitor sensitivity . This approach reduces subjectivity and variation during sample and image processing.
WebThe defect correlated with reduced Homologous Recombination (HR) repair, as demonstrated by the reduction of RAD51 foci formation and by direct evaluation of HR … Web14 jun. 2024 · It was afterwards theorized how HR defective hypoxic cells could be sensitive to PARPi, irrespective of their BRCA status, which was proven true in various cell lines. The most effective result was observed in cells subjected to severe hypoxia, followed by reoxygenation, probably because of the synergistic effect of reactive oxygen species …
Web5 mei 2011 · HR defective cells that are unable to repair HR-inducing lesions are normally very sensitive to agents causing such lesions. Surprisingly, we find that DRB has no UV … WebMoreover, since HCT116 is an HR-proficient cell line (63, 64), these results suggest that some of these other defects affect pathways other than HR. This result, which is predicted from S. cerevisiae SL networks, indicates that it would be interesting to establish the identity of the other defects that cause FEN1-inhibitor sensitivity in human cells.
